Mode 3

Pin D2 is LOW, pin D3 is HIGH and pin D4 is LOW. This Mode is ideal for turning ON the Sockets with an automated text.

A short number of rings is sufficient to turn ON the socket, under 20 second back light time.

The socket only stays ON for approximately 1 second.

See Mode 1 for explanation of backlight timings.
